Baader-Meinhof Phenomenon
Once a concept is named, your altered attention makes it seem newly ubiquitous. The apparent surge may be in recognition, not in the world.
You hear the name Baader-Meinhof phenomenon once—and then seem to encounter it everywhere. Nothing outside you had to multiply; one new label was enough to make previously unremarkable instances visible.
E1A name changes the filter
Before the concept has a name, matching instances are easy to overlook or forget. Naming supplies a recognizable pattern: attention can now select it, and memory can register each match as another occurrence. The resulting cluster feels like evidence that the phenomenon has suddenly become common, even though what changed may be your ability to detect it. This is a form of Top-Down Processing: the new concept tells perception what to look for.
E1Visibility is not frequency
The effect cannot tell you whether the underlying frequency stayed constant. Something may genuinely be becoming more common at the same moment you learn its name. Conversely, repeated sightings alone do not establish a real increase; you need observations from before and after your attention changed.
Count instead of concluding
When a newly learned idea starts appearing everywhere, record each sighting for a week and distinguish unsolicited encounters from ones found while actively looking. Treat the list as evidence of what you noticed—not yet as evidence that the world changed.
